Blank are renewable resources because they can be replaced in a short time. Blank are nonrenewable resources because they cannot be replaced or can only be replaced over millions of years

Plants and animals (such as trees and fish) are renewable resources because they can be replaced relatively quickly through natural processes like growth and reproduction. Fossil fuels (such as coal, oil, and natural gas) are nonrenewable resources because they cannot be replaced or can only be replaced over millions of years due to their formation process involving geological processes and the decay of organic matter.

Blank are renewable resources because they can be replaced in a short time. Examples of renewable resources include:

1. Solar energy: The sun is a renewable resource that provides energy through solar panels, which convert sunlight into electricity.

2. Wind energy: Wind is a renewable resource that can be harnessed by wind turbines to generate electricity.

3. Water (hydro) power: Flowing water, such as rivers and streams, can be used to generate electricity through hydroelectric power.

4. Biomass: Organic materials such as crops, wood, and agricultural waste can be used to produce energy through processes like burning or fermentation.

5. Geothermal energy: Heat generated from the Earth's core can be tapped into and utilized for heating and electricity production.

On the other hand, blank are nonrenewable resources because they cannot be replaced or can only be replaced over millions of years. Examples of nonrenewable resources include:

1. Fossil fuels: Oil, coal, and natural gas are finite resources that were formed over millions of years. Once extracted and consumed, they cannot be replaced within a reasonable timeframe.

2. Minerals: Certain minerals, such as metals like iron, copper, and gold, are nonrenewable as they are mined from the Earth's crust and cannot be replenished.

3. Nuclear fuel: Uranium, which is used as fuel in nuclear power plants, is a nonrenewable resource that is in limited supply and takes millions of years to form.

It is important to manage and conserve nonrenewable resources as they are being depleted faster than they can be replenished, whereas renewable resources offer a sustainable and environmentally friendly alternative.
